As atmospheric river exits, a new storm threatens California
WATSONVILLE, Calif. — Wet, miserable weather continued across huge swaths of California on Sunday as an atmospheric river that caused major flooding flowed eastward, while a new storm threatened another onslaught of rain, snow and gusting winds as soon as today.
The National Weather Service said the next system could exacerbate severe flooding that overwhelmed the area in recent days, prompting a levee failure and widespread evacuations Saturday in farming communities near the state’s central coast.
The new storm is not expected to bring as much rain, but forecasters warned that “considerable flooding” could occur at lower elevations from additional rain and creeks and streams swollen with snowmelt.
“Definitely prepare for some more flooding impacts. The ground is very saturated. We’re already seeing some impacts from some light amounts,” National Weather Service forecaster Eleanor Dhuyvetter said.
A tornado briefly touched down in Tuolumne County during severe thunderstorms Saturday that also dumped an inch of hail, the weather service office in Sacramento said. Tornadoes were possible again Sunday afternoon, forecasters warned.
Today’s incoming rain and snow is expected to extend from central California to Oregon and northern Nevada. Wind gusts of up to 50 mph are expected in some places and could damage power lines and snap tree branches.
But the new storm is moving fast, meaning it won’t have time to dump as much rain.
Over the past two days, more than 20 inches of snow fell at a measuring station in the Sierra Nevada, and more is expected. The snowpack is now nearly twice the average, and the highest in about four decades, according to UC Berkeley’s Central Sierra Snow Lab.
The snowpack stores much-needed water for a state seeking to emerge from a three-year drought.
As much as a foot of rain fell in the Big Sur area of the state over a two-day period, weather data.
Authorities suggest that residents have a plan in case further evacuations orders are issued.
Across Monterey County, more than 8,500 people were evacuated Saturday, including roughly 1,700 residents — many of them Latino farmworkers — from the unincorporated community of Pajaro.
“We are still in disaster response mode,” said Monterey County spokesman Nicholas Pasculli on Sunday. He said the county is staging high water rescue teams around the county and opening more shelters in anticipation of more flooding.
Highway 1, also known as the Pacific Coast Highway, is closed at several points along Big Sur as well as near Pajaro due to flooding.
The atmospheric river, known as a “Pineapple Express” because it brought warm subtropical moisture across the Pacific from near Hawaii, was melting lower parts of the huge snowpack in California’s mountains.
Because of the massive flooding over the early weekend, more than 50 people had to be rescued by first responders and the California National Guard. One video showed a Guard member helping a driver out of a car trapped by water up to their waists.
The extent of property damages was still uncertain but Luis Alejo, chair of the Monterey County Board of Supervisors, sought help from the state and federal governments.
“The need will be great! Will take months for our residents to repair homes!” he wrote in a tweet Saturday.
Gov. Gavin Newsom has declared emergencies in 34 counties in recent weeks, and the Biden administration approved a presidential disaster declaration for some on Friday morning. President Joe Biden spoke with Newsom on Saturday to pledge federal support for California’s emergency response, the White House said.
